Title: Improvements in and relating to crankless engines, pumps, compressors and the like
IPC: F16H23/02
Filed: 1926-05-18
Abstract: 276,072. Rutherford, R. May 18, 1926. Cam - actuated pumps; stroke, varying. -A multiple-cylinder engine, pump, or compressor of the swash-plate type has a longitudinally adjustable shaft which engages the driven or driving-shaft through screw and nut mechanism, and the swashplate is connected by link mechanism to a flywheel wheel so that variations of the load on the main shaft or of the power applied thereto varies the strokes of the pistons. The swash-plate is in two parts c, c<1> and is connected to the pistons by ball-ended connecting-rods a<1>, and to a, sleeve k which surrounds the shaft e<3> and is splined and slides in bearings b<5> by a gimbal ring h. The swash-plate carries a driving-ring d mounted on ball or roller bearings d' which are connected by ball joints to two standards e<1> on a, flange e<2> secured to the shaft e<3>, and to two rods g<1>, g. One rod g is pivoted at g<2> to a lever f<4>, which is pivoted at one end to the periphery of the flywheel and at the other end to a pin f<5> on the shaft e<3>; the other rod g<1> slides in a guide g<3> in a similar lever f<4>. The engine shaft e<3> is slidably keyed to a sleeve f which carries the flywheel, and screws into the main shaft m against the resistance of a spring n. A variation in the power of the cylinders due to an adjustment of the throttle or a variation in the load on the shaft m causes the shaft e<3> to screw to the left or right and effect a balanced position against the resistance of the spring n. Hand adjustment of the swash-plate may be effected by a grooved collar p. The Provisional Specification describes a double-acting arrangement with the swash-plate between the cylinders engaging the pistons through blocks carried thereby engaging an annular ring forming part of the swash-plate.

Title: Improvements in or relating to the bonding of metal to moulded compositions
Inventor: CAPEWELL GORDON ARTHUR
IPC: B32B15/08
Filed: 1953-05-07
Abstract: A method for forming a moulded product embodying as a surface layer a metal component comprises the provision of a layer comprising an amino-formaldehyde resin between the said surface metal component and a mouldable composition comprising a filter and a bonding agent, the provision of a layer of adhesive between the amino-formaldehyde layer and the metal component and subjecting the assembly to moulding conditions.  The term "metal component" includes metal sheets, foils and blocks.  The amino-formaldehyde resin layer may be in the form of a supported or an unsupported film; it may be applied to a sheet of fibrous material such as paper or it may be applied as a solution to the adhesive-treated metal component.  The adhesive for the metal may be applied to the metal component or to a sheet of paper treated with amino-formaldehyde resin or to both, or it may be interposed between the metal and the amino-formaldehyde layer as a supported or unsupported film.  The metal surface which may be of aluminium or copper, may be etched before bonding.  The filter may consist of sheets of paper, wood plies, or moulding powder comprising wood flour or clay and asbestos fibres.  Specified adhesives are phenol formaldehyde resin and polyvinyl butyrol resin dissolved in organic solvent, and a solution in methyl ethyl ketone of a copolymer of butadiene and acrylonitrile plasticized with dioctyl phthalate. Melamine formaldehyde and urea-formaldehyde are mentioned as amino-formaldehyde resins.  Specified bonding agents for the fillers are cresol-formaldehyde resin, phenol formaldehyde glue and dialkyl phthalate resin.  Examples disclose the formation of laminated products by assembling the layers and then compressing them at elevated temperatures.

Title: Process for the recovery of micro-organisms
Inventor: BONAVITE JEAN-BAPTISTE
IPC: C12C11/00
Filed: 1967-03-20
Abstract: 1,213,651. Recovering micro-organisms from their culture media. BRITISH PETROLEUM CO. Ltd. March 7, 1968 [March 20, 1967], No.12840/67. Heading C6F. A mixture consisting of or containing a microorganism and aqueous phase is treated to reduce the PH of the aqueous phase, the treated mixture is subjected to a phase separation treatment (decantation) to remove part of the aqueous phase, the residual mixture is treated with a diluent which is a water-soluble oxygen-containing organic compound having a specific gravity less than 1 whereby the specific gravity of the aqueous phase is reduced, and the treated residual mixture is centrifuged to recover a fraction having an enhanced concentration of micro-organism. Adjustment of the pH may be effected with phosphoric, sulphuric or hydrochloric acids. Diluents: ethanol, propanol, isopropanol, n-butanol, 2-butanol and acetone. The diluent is added to the mixture to be treated in a ratio, by weight, in the range 0À5:1 to 2:1. Many species and strains of micro-organisms (yeasts, moulds and bacteria) are particularly mentioned. The process may be employed for the treatment of a broth obtained in the aerobic cultivation of a micro-organism upon a hydrocarbon substrate. The substrate may be a mixture containing metabolisable hydrocarbons and non-metabolisable hydrocarbons. According to an example, the broth obtained from the cultivation of Nocardia erythropolis on a gas oil of specified characteristics was acidified by addition of 5N sulphuric acid until the pH had fallen to 2À5. Two liquid phases were obtained and the upper phase, containing the micro-organism and residual hydrocarbon, was separated by decantation, stirred with an equal volume of ethanol and then centrifuged at 10, 00 g. A paste containing micro-organisms, recovered from the centrifuge, was diluted with four times its volume of ethanol, again centrifuged at 10, 000 g and the product, free of hydrocarbons and ethanol, was then dried. No phase separation took place when the centrifuging was carried out without such addition of ethanol. A further example relates to the recovery of micro-organism from a cultivation broth containing as substrate C9-C19 normal paraffins obtained from a petroleum kerosene fraction by molecular sieve extraction.

Title: Insulated electrical conductor and method of making same
IPC: H01B3/44
Filed: 1954-05-04
Abstract: An electric conductor is insulated with a layer of natural rubber or a rubbery butadiene-styrene copolymer, a tie layer comprising a mixture of the same kind of rubber, a vinyl resin and an oil-resistant copolymer which is a plasticizer of the vinyl resin, and a protective layer comprising a mixture of the same vinyl resin and plasticizer, the rubber being vulcanized and the layers coalesced at their interfaces.  The tie layer preferably contains from 10-70 per cent by weight of the rubber and from 90-30 per cent of the vinyl resin and plasticizer, and may be applied as two or more coatings, the inner containing a higher proportion of rubber than the outer. The vinyl resin may be polyvinyl chloride or a copolymer of vinyl chloride with a lesser amount of copolymerizable monomeric compound containing as its sole unsaturation a single olefinic double bond, such as vinyl acetate, vinylidene chloride or diethyl maleate.  The plasticizing copolymer may be derived from butadiene and acrylonitrile, containing from 15-40 per cent by weight of combined acrylonitrile.  The proportion of vinyl resin: plasticizer in the tie layer and protective layer may be from 50 : 50 to 80 : 20. The layers are preferably applied to the conductor as latex dispersions.  The vinyl resin and plasticizer latex may be produced by adding the monomeric components of either the vinyl resin or the butadiene-acrylonitrile copolymer to a preformed latex of the other and polymerizing the added monomeric components in this pre-formed latex itself.  A stabilizer such as an organo-metallic compound containing tin or lead may be added to increase light-fastness. Specification 557,268, [Group VIII], is referred to.

Filed: 1933-05-06
Abstract: 419,301. Coin-freed article-delivery apparatus. LUCAS, T. S., and FRETWELL, C. M., 5, Wine Office Court, Shoe Lane, London. May 6, 1933, No. 13244. [Class 27.] Articles stored in separate compartments.- Bottled goods 21 are stored in separate compartments covered by flexible sliding shutters 2, 3, carried on a hinged frame 12, and operable step-bystep for successive prepayments. The shutters comprise elements 22 coupled by cross-pins 23 running in channelled guideways 24, and are provided on their under side with a series of projections 43 adapted to pass between adjacent pairs of a row of locking members 25-30, mounted for limited lateral movement between oppositely acting spring urged levers 32, 33. Normally member 30 is locked, so that the projections 43 cannot pass between the locking members, but after prepayment, member 3U is permitted such limited movement to the right, that a projection 43 on one shutter can pass between the locking members to give access to a compartment. The apparatus shown is for vending bottles containing the same commodity, and extensions 46 on the locking members engage the projections 43 to prevent opening of a shutter until all shutters to the right thereof are fully open. Where the commodities covered by the several shutters differ, and the customer is permitted a choice, projections 46 are omitted, and a second set of non-coin-freed locking members, extending in front of locking members 25-30, are provided, to prevent fraudulent further operation of the shutter after a single prepayment by frictionally engaging a locking member with an adjacent shutter. Coin-action, mechanical connection.-Member 30 is normally retained by a latch 42 pivoted at 40. An inserted coin 44 enters a space between member 30 and the latch which is thus raised out of engagement with member 30 when it is operated.

Title: Vehicle starting systems
IPC: F02P11/00
Filed: 1973-03-22
Abstract: 1465265 Starting prime movers LUCAS ELECTRICAL Ltd 13 Feb 1974 [22 March 1973] 13783/73 Heading H2H A system for starting the engine of a vehicle is so arranged that restarting of the engine after an attempt has been made to start the engine is inhibited until the starter switch has been released from the starting position. A battery 16 of a vehicle is charged by an alternator 11 by way of a rectifier bridge 12, 13 and conductors 14, 15. A series circuit comprising a starter switch 19, contact 25 of a first relay and winding 26 of a second relay is connected across the battery 16 such that when the starter switch 19 is in the starting position 22, the winding 26 is energized to close contact 27 so energizing winding 28 of the starter relay to close contact 29 whereby to energize the starter motor 31. When the engine is running the alternator 11 produces an output on a conductor 18 by way of rectifier diodes 17 such that the conductors 18, 14 are at the same potential. Winding 34 of the first relay is thus energized sufficiently to change over the contact 25 whereupon winding 26, and hence winding 28 and the starter motor 31, are de-energized. The change over of the contact 25 also places the winding across the battery 16 so that it remains energized should the alternator 11 cease to provide an output. Thus to operate the starter motor again the switch 19 must be released from the starting position 22 in order that the system may revert to the normal condition. A warning lamp 24 is provided and a conventional regulator 33 for the alternator field winding 22. The winding 34 receives current via the lamp 24 during the initial stages of a starting operation but this energization is insufficient to cause operation of the first relay.
